In the launcher, or you can use UnX and change it in the .ini.

You can switch the language in the launcher, however you can only switch BOTH text and audio to the same language. You cannot have them be different with the default game.

To do that you'll need a mod, like UnX mentioned above.

A launcher at the start of the game will allow you to select one of the following language setups:
*Audio is restricted depending on the language setting*

• Text: Japanese / Korean / Traditional Chinese WITH Voice: Japanese
• Text: English / French / Italian / German / Spanish WITH Voice: English

We know a lot of you have been asking whether there are dual audio options but unfortunately due to technical reasons, we’re not able to include dual audio in FFX|X-2 HD Remaster.

Thank you, guys, I got it working. I set the audio to English and the subtitles to my language, Brazilian Portuguese.

Use "untitled project x"
